Problems solved by technology

The present invention uses natural plant flower powder (lotus leaf powder, rose powder, lavender powder, citronella powder, jasmine powder, green tea powder, mulberry leaf powder, chrysanthemum powder, plum powder, osmanthus powder, etc.) as fillers to replace traditional mineral fillers At the same time, the bubble body is colored and scented with natural plant pigments and the smell of flower powder, which solves various problems caused by traditional fillers, color pastes, and flavors, and at the same time gives certain care and health care effects to the bubble body (such as The volatile oily substances contained in jasmine have the functions of promoting qi and relieving pain, relieving depression and resolving stagnation; lavender essential oil has the effect of helping sleep, etc.), which reduces the density of traditional slow-rebound polyurethane foam pillows and avoids the use of traditional color creams The possibility of water pollution increases the fragrance retention time of the foam body and avoids the possibility of skin irritation caused by colorants and essences

Abstract

The invention discloses a slow-resilience polyurethane foamed pillow containing plant flower and grass powder, and a preparation method thereof. The process of a traditional slow-resilience polyurethane foamed pillow is improved, natural plant flower and grass powder is adopted as a filler to replace a traditional mineral filler, and natural plant pigment and the smell of the flower and grass powder are utilized to color and endow foam bodies with fragrance, so various problems caused by traditional filler, color paste and essence are solved, meanwhile, the foam body is endowed with a certain nursing and health care effect, the density of a traditional slow-rebound polyurethane foam pillow is reduced, the possibility that a water body is polluted by using the traditional color paste is avoided, the fragrance retention time of the foam body is prolonged, and the possibility that the color paste and the essence stimulate the skin is avoided.

Description

technical field [0001] The invention relates to the technical field of slow-rebound polyurethane foaming, in particular to a slow-rebound polyurethane foam pillow containing plant flower powder and a preparation method thereof. Background technique [0002] At present, light calcium carbonate is often used as the main filler in the foaming of traditional polyurethane slow-rebound pillows or no filler is used, the foam body is colored with mineral-type color paste or resin-type color paste, and the foam body is scented with essence. This will cause the following problems: light calcium carbonate, kaolin and other fillers will increase the quality of the foam body; color pastes are easy to decolorize and contain heavy metal elements, such as lead compounds, etc.; flavors are volatile and cannot last for a long time. Skin allergies. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a slow-rebound polyur...
